Abstract: Objective：To explore the clinical effect of uterine cavity shaped ballon and intrauterine device (IUD) in preventing intrauterine adhesion (IUA) after hysteroscopic transcervical resection of uterine septum (TCRS). Methods: The clinical data of 65 patients with septate uterus were retrospectively analyzed. After surgery, 30 patients (group A) received uterine cavity shaped ballon and hormone replacement therapy, 35 patients (group B) received IUD and hormone replacement therapy. The hysteroscopic examination was performed after 3 months of surgery, the IUD was removed. The patients′ data were collected including menstruation, vaginal bleeding and lumbar or abdominal discomfort. Results: No IUA occurred in the two groups. During 3 months after surgery, in group A no lumbar or abdominal discomfort and abnormal uterine bleeding occurred，in group B 2 cases incarceration of IUD occurred with the incidence of 5.71%, 6 cases of lumbar or abdominal discomfort occurred with the incidence of 17.14% (P=0.027), 10 abnormal uterine bleeding occurred with the incidence of 28.57% (P=0.001), these symptoms relieved after removing IUD. Conclusions: No difference between the groups in preventing IUA after TCRS. Because of the side effects of IUD, uterine cavity shaped ballon is a more appropriate method.
